SCRAPER SHOE (PLASTIC)
The Scraper shoe is designed to be able to ip end for end when worn. This gives the operator an
extended use before replacing. To either ip or replace the shoe remove the 3 bolts. With a new shoe,
it may be at when purchased. To mould this into an arc form simply place shoe between the jaws of a
vice and over bend , replace bolts – bottom rst.
HEAVY DUTY SCRAPER SHOE (METAL)
The Heavy Duty scraper shoe is designed to be used with the Hydrive XD and the Bigfoot XD.
3. When pressing the new bearing in ensure the drift used is
the correct size. ie; The drift must sit against the outside shell of
the bearing being careful not to damage the ring that holds the
bearing together, make sure the bearing is sitting against the lip on
the opposite side of the nose roller and replace circlip.
